Y HAND-TRUCK.

SPECIFICATION forming part of Letters Patent No. 373,795, dated November22, 1887.

Application filed February 3, 1887. Serial No. 226,466. (No model.)

To all whom it may concern:

, Be it known that I, OHARLEs F. BEAMAN, a citizen of the United States,residing in Brooklyn, Kings county, New York, (assignor to JOSEPH ANNIN,of same place,) have invented an Improvement in Hand Trucks or Barrows;and I do hereby declare that the following-is a full, clear, and eXactdescription of the same,

referring to the accompanying drawings, form- 4- of strength, a morerigid and secure fastening trucks or barrows.

for such side pieces to the body of the truck, and the combination,withsuch side pieces, of more convenient handles.

Hitherto the side pieces of tubular barrows or hand-trucks have beenmade of round tubes or sections of round metal pipes fastened to thebody with clips tightened upon the tubular side pieces by bolts andnuts.

Tubes or pipes of circular cross-section, if of uniform thickness, areequally strong to resist strains in any direction. Consequently, whenused for the side pieces of hand trucks or barrows, they are no strongerto resist force applied in such manner as to tend to bend them in avertical plane than they are to resist strains at right angles to suchplane; but it is well known that the strains of the first-mentioned kindare those to which they are constantly subjected, and that they are farmore severe than those applied at right angles to the vertical plane. Itis obvious, therefore, that the correct principle upon .Which toconstruct these pieces, in order to secure lightness without sacrificeof strength, or to increase strength without undue weight, is toconstruct them in such manner that they are stronger to resist verticalthan horizontal strains. This is attained by flattening the tubessomewhat at the sides, thus imparting to the tubes an oval cross-sectionlonger in vertical direction; and my present invention consists, partly,in such construction of the side pieces of hand Moreover, as the clips,which embrace and clamp the side pieces of oval cross-section, do nothold such side pieces whollyby friction, as is the case with side piecesof round tubing, they may be and are made in my present improvement muchlighter, and are closed together by lighter and smaller bolts and nutsthan are necessary for round tubes; and myinvention further consists ina construction in a hand truck or barrow of tubular side pieces havingan oval crosssection and a body provided with clips havingcorrespondingly-shaped bearings for embracing and holding said sidepieces, as hereinafter set forth; but the oval shape of the section ofthe side pieces is not agreeable to the hand of the workman when suchsection is continued throughout the entire length of the same, handlesand all, and its size necessary to give the requisite strength isgreater than is needed for the handles proper. I therefore not onlyreduce the ends of the side pieces to form handles of a convenient size,but also make these handles of circular cross-section, and thesepeculiarities of construction also form features of my invention.

Referring now to the drawings, Figure 1 is a front or top View of a handtruck or barrow constructed in accordance with my improvement. Fig. 2 isa crosssection made on the line was in Fig. 1. Fig. 3 is a longitudinalsection made on the line ww in Fig. 1. Figs. 4, 5, and 6 arerespectively a longitudinal section ofa portion of one of the sidepieces and the handle of the same and cross-sections made onthe lines yy and z z in Fig. 3.

A represents the body of the truck, which is in this example of myinvention made of cast-iron in a single piece, and which has formed uponit or thereunto attached clips a. The cross pieces I), which join thesides of the body, are concaved in the usual manner for the safe supportof casks or barrels. The sides of the body so joined are each made witha channel, 0, on the under side, as best shown in Fig. 2.

Each side piece, .13, is passed through the clips (1 and channel 0 onone side of the truck, and its lower end is inserted into a socket, d,cast on the body of the lower part, as shown in dotted outline in Figs.1 and 3.

The handles are shown at H. They are of circular cross-section, and arerepresented as covered with some non-conducting material,

preferably of seamless tubes 7:, of toughened or parchmentized paper, asshown best in Fig. 4.

A cross-section of one of the side pieces is shown in Fig. 6. It will beseen that this sectron is oval in form, or that at top and bottom it iscircular, and fiat at the sides. It is easily made from ordinary roundpipe or tubing fiattened by dies or other methods well known in the art,and which need not therefore be here described. This oval side piece maybe oined to the handle by ashort portion of tube, whlch is notflattened, but is left of the original round cross-section, as shown inFig. 5, and which is lettered e in Figs. 1, 3, and 4. The handle portionH is, however, preferably smaller than the part 6, as well shown inFigs. 3 and 4, being so reduced by rolling, while the non-conductingtube It is slipped over the reduced portion, so as to be flush, ornearly so, with the part c.

The parts B, e, and H are made from a single piece of tubing or pipe,and are continuons one with another, as shown.

The channels 0 in the side pieces of the body are, in cross-section, theform of the upper half of the perimeter of the cross-section of the sidepieces, B, as shown in Fig. 2, and from the lower margins of thesechannels extend downward the clips a ,which embrace the side pieces andfirmly retain them in said channels and in the aforementioned sockets d.

The clips are tightened upon theside pieces by boltsfand nuts 9, two ofthe clips also serving as attachments for the angular supports K.

It will now be seen that the construction I have described attains theobjects of the improvement above set forth in an extremely cheap andsimple manner. It enables me to produce a much lighter handier truck orbarrow of a given strength than can be produced by the use of roundpipes or tubes, and to use lighter clips and bolts than can be used forattaching circular side pieces to the body of the truck. At the sametime a convenient handle, not disagreeable on account of size or shape,is supplied.

Having thus described my improvement, what I claim as my invention, anddesire to secure by Letters Patent, is as follows:

1. The combination,with the body of a hand truck or barrow havingchannels 0 and clips a,with oval contours, of side pieces, B, having incross-section a similar contour fitted into said channels and clips andembraced by the clips, substantially as and for the purposes set forth.

2. The combination,with the body of a hand truck or barrow, of tubularside pieces, B, of oval cross-section, having handles H,a1so tubular andof circular cross-section, formed in one piece with said side pieces,substantially as and for the purposes described.

3. The combination,with the body of ahand truck or barrow, of tubularside pieces, B, of oval cross-section, having handles H,also tubular,circular in cross section, smaller in diameter than the side-pieces, andformed in one piece with said side pieces, substantially as and for thepurposes specified.

4. In a hand truck or barrow, the combination, with the main part of thetubular side pieces, B, having oval cross-seetion,of tubular handlesH,of smaller diameter than that of the side pieces and circular incross-section, and tubular joining parts 6, also of circularcrosssection,of a diameter larger than the handles, and connecting saidoval parts with the haudles, said oval parts, handles,andjoining partsof each side piece being formed of one piece of tubing or pipe,substantially as and for the purposes set forth.

5. In a hand truck or barrow, the tubular side bars, B, made of ordinaryround pipe flattened into oval form along the main portion attached tothe body of the barrow, but left round at the handle extremities,substantially as shown and described.
